It's not that Feng Jun doesn't want to deduce for Nascent Soul Middle Phase and High-Rank levels, it's just that to deduce them, one must take a trip to the Tianqin Main Plane.
This time is no exception, not only did he make a special trip, but he also brought along Yi Jue, Qian Zhong, and Xuanyuan Buqi.
Bringing Yi Jue was easy to explain, but those two True Sages insisted on coming along without providing a reason—though, is it necessary to ask?
Feng Jun estimates that until he takes out another Soul Exit Pill, these two True Sages won't leave him.
Feng Jun has also deduced the obstruction in Ji Niang True Immortal's advancement, which lies in some minor karma in a certain lower realm besides some flaw in her foundation. Her mentor, True Sage Liu He, also deduced the flaw, but not the minor karma.
With Feng Jun's current ability, he cannot deduce the specifics of the karma, he can only hint at them slightly, while recommending some advancement items.
